# timetable-bin - prebuilt package of https://codeberg.org/ostfriese4/untis
# ("Timetable", a GTK4 + LibAdwaita WebUntis client written in Python).
#
# Upstream publishes no binary release assets, so build_artifact() builds the
# app from the release tarball and the resulting install tree is published as
# a GitHub release asset of this repository, which the PKGBUILD then uses.

UPSTREAM_REPO="ostfriese4/untis"

# Installed in CI (pacman) before build_artifact runs.
